The more I think about this I think it boils down to "at what level?" I think pemerton makes some good points, here - the difference between wanting to know that a character tries to physically harm another creature and wanting to know the angle of the sword cut they make, the bodily manoeuvre used and the justification of any and all subsequent effects is one of degree, not fundamental quality. Is it sufficient to know simply that the character is good at this stuff and, depending to some extent on chance, may get certain results from doing it - or do we need to know how and why they achieve these results in detail? And, if the latter, what specific detail, exactly? In the former, aspects of the setting - that this sort of result is possible, that the situation is suitable to achieve such a result and that this character is good at getting these results, for example - are important. The only difference, perhaps, is that it is the player's decisions of character intent, rather than their justification of their desired result, that has effect.
That is food for thought! I think you and [MENTION=42582]pemerton[/MENTION] are right - it is a matter of degrees. I don't care about how much and what kind of food or drink a PC consumed before the fight, even though I know that would have an effect on its outcome. (I might add a -2 penalty if the character is drunk, but that's about it.) Thinking about it, that fine detail of actions is a personal preference of mine; it's probably why I've always preferred Palladium Fantasy's combat system over D&D's. (Yes, seriously!

)
I think I might have to change my point of view that focus on the real-world things at the table - the battlemat, the minis - takes away from focus on the fictional details; those are representations of the fiction, in as much detail as most people want. I just want more!
Here's an example of a combat from Tuesday in my hacked system:
[sblock=Hacked]Example: Playing on Tuesday. The PCs are in "Stormwatch"
1, which is a city made of huge towers built into a basalt cliff face. The PCs are crossing an open-air bridge on the third level, 120 feet or so above the ground, with no railings
2.
Dhalia Doomfey, an emaciated Fighter/Warlock in the AD&D multiclass style, was alerted to danger on the bridge thanks to her almost-supernatural martial awareness
3. The other PC, Kronos the Exsanguinator, opened the far door using
Mage Hand. Dhalia threw a grappling hook into the far room, catching hold of the door, and the two carefully crossed.
Suddenly a grappling hook appeared from out of nowhere and latched onto Kronos
4. A leather-clad woman was hanging onto the side of the tower using some kind of magic. She yanked and tugged on the rope, dragging Kronos off the bridge, but the wily mage held fast onto Dhalia's rope and used it to swing onto a bridge beneath them. As Kronos fell, Dhalia grabbed onto the NPC's rope, braced herself, and pulled with all the might her
Gauntlets of Ogre Power could give. The NPC came tumbling from the wall
5.
As Kronos ran to get back into the fight, the NPC drew her blade defensively and rose, then leapt off the bridge to the tower wall, where her
Spider Climb spell would allow her to latch on. Dhalia grabbed her sword hand before she could slip away and followed up with a knee to her chest, pinning the would-be assassin - half-off the bridge, one hand on the tower wall, her sword hand in Dhalia's crushing grip.
6
Dhalia forced the NPC's sword to her throat while calling for her surrender, but the NPC was saved by her leather armour
7. The NPC whispered a
Sleep spell but Dhalia easily resisted.
1 - Stormwatch was an established city name in the campaign, but I am using Vornheim for it.
2 - I didn't know from the map of the tower if the bridge had a railing, so I rolled 1d6 to determine how much. I got a 1 - no railing.
3 - The Invisible NPC rolled a check to hide, but didn't hit Dhalia's passive score - 10 + 1/2 level + stat + skill, Martial Awareness the skill in this case. Dhalia could not actually see her, but I said, "The hairs on your neck stand up; there's danger out there." This is a feat that would not have been possible at Heroic tier - she would have needed to look out and around - but Dhalia is a Paragon tier character and is almost supernatural.
4 - The NPC made a check (level + 3) against Kronos' Ref defence and succeeded.
5 - The NPC made a check (level + 3) against Kronos' Fort, succeeded; Kronos didn't need to roll anything, because his action - swinging down - wasn't opposed; Dhalia made a check (1/2 level + Str mod + her Gauntlets of Ogre Power skill + a bonus for bracing herself) against the NPC's Fort - with a bonus for Spider Climb - and succeeded.
6 - The NPC took a defensive action - drawing her sword and leaping away, which netted her a +4 bonus to her Fort defence; Dhalia made the same check as above, this time with a +2 because the NPC was on the ground and a +2 because this action built directly off her previous action. Dhalia succeeded easily.
7 - This time Dhalia's bonus for building off previous actions was +4.[/sblock]
Here's the same thing, but in 4E's general rules:
[sblock=Regular 4E]I draw the map and tell players that it's 120' to the ground. I make the Stealth check for the NPC against the Passive Perception, and fail. The PCs notice the invisible NPC.
The NPC wins Init and throws the grappling hook, for which she has a special power - Ranged 5, Level + 3 vs. Fort, Hit: 1d6+4 damage, Pull 3 and Grabbed. She hits. Kronos is Pulled, but makes his hazardous terrain saving throw to avoid falling.
Dhalia grabs the rope and attempts to pull the NPC adjacent to her using an action the rules don't cover; I cast the attack as a check, saying it does no damage but instead Pull 5 and Prone. Dhalia attacks using Str vs. Will (because of the Spider Climb) and succeeds.
Kronos drops down to the next level using their rope.
The NPC rises from Prone and Climbs away, triggering an AoO. Dhalia misses, then moves adjacent to the NPC and Grabs her.
The NPC casts Sleep and misses; Dhalia takes an AoO and misses. Dhalia makes an Intimidate check calling for her surrender and as DM I make a judgement call that, even though the NPC isn't Bloodied, she will surrender on a successful roll. Dhalia succeeds.[/sblock]
I can see how the rules - positioning, terrain, spells cast, the ropes, the powers, actions taken - are all part of the fiction in 4E; what they are missing from my hack are those fine details. How does Dhalia notice the invisible NPC? How does Kronos save from falling off the bridge? How does Dhalia Grab the NPC? What is she doing when she takes her AoO? I really want those fine details!
Heh - good point! I should have said "all of them", maybe...
Basically, I enjoy both games where the action is described in a very general, abstract way (with the in-game outcome described in an arbitrary manner post-facto) and games where the action is detailed down to the intended sword cut angle (Riddle of Steel, anyone?) before the outcome is determined.
I also enjoy both games where the rules define the world-setting "physics" for both the GM and the players, with GM discretion dialled to a minimum and tactical competition to the fore, and games of collaborative world-building, where the world "physics" is defined by mutually agreed aesthetics, subject only to consistency with what has been settled upon before, during play.
I tend not to enjoy games where the
in-game outcome of an action doesn't have an influence on resolution of any future actions. If I use my spear to push back a kobold with a rusty dagger, and the fact that I pushed him back and should have some kind of reach advantage doesn't change future resolution, I stop describing what I'm doing in-game.
